About the Project

Degradation is happening to the Missouri River, and it could cost the region billions of dollars in damaged infrastructure and lost business revenue. The U.S. Army Corps of Engineers, the Mid-America Regional Council and local community partners collaborated to execute a study of the degradation and to learn what could be done to prevent it. The study did not result in the development of a recommended plan for implementation and no further study efforts will be conducted. A technical report has been prepared to document and present information regarding the evaluation conducted and the technical findings of the project.

Final Technical Report

Public scoping meeting - 2014

MARC and the Corps of Engineers hosted a public scoping meeting on March 11,2014. The meeting provided an opportunity for citizens to contribute their ideas about what issues the study should address and other related concerns. The Public Scoping Report describes the public scoping process and summarizes input received from scoping (12 MB PDF).

The Deadline for Public scoping comments was March 31, 2014. Except where subject to the confidentiality provision of the National Historic Preservation Act, all comments will become part of the public record and may be included in public documents.


The Study

The Missouri River Bed Degradation Study was a multiyear study that will assessed riverbed degradation between Rulo, Nebraska., and St. Louis, Missouri., focusing on the stretch of river in the Kansas City area, where degradation is the most severe (see study area at right). The study determined the causes of degradation, explored how future degradation can be prevented, and recommended ways public infrastructure can be protected. Read the Missouri River Bed Degradation Feasibility Study Report Synopsis»

Prior work

The Kansas City District of the U.S. Army Corps of Engineers (USACE) conducted an initial reconnaissance study in 2009 to study degradation on the Missouri River. The study stretched from Rulo, Nebraska, to the mouth of the river in St. Louis, Missouri.

The study examined existing data to determine the current condition and potential future condition of the riverbed, and looked for opportunities to reduce bed degradation and its impacts. The corps determined through stream-gage and other physical data that there has been a lowering of the riverbed. The bed degradation has affected public infrastructure, such as water intakes and pipeline crossings; bank stability in certain areas; and potentially could undermine dikes, revetments and levees designed to support navigation and to provide flood protection.

This study laid the foundation for the Missouri River Bed Degradation study, for which Congress authorized and appropriated funds in FY2010. Public and private organizations partnered with the USACE to support the costs.
